Running Oracle XE 11gR2 in Nova-Docker container on OpenStack RDO Juno (CentOS 7)

*****************************
UPDATE as of 12/30/2014
*****************************
Today's Big Story @LXER.com

 

Docker image arahman/docker-oracle-xe-11g:latest  allows to build Nova-Docker
Container on RDO Juno running Oracle XE instance, which may be accessed remotely via floating IP assigned to nova instance. Several network configuration files require tuning with Nova system  instance-name and floating IP assigned
from neutron external pool.

   Nova-Docker driver  has been set up on RDO Juno per http://www.linux.com/community/blogs/133-general-linux/799569-running-nova-docker-on-openstack-rdo-juno-centos-7

   Docker image arahman/docker-oracle-xe-11g:latest to be pulled in is provided by https://registry.hub.docker.com/u/arahman/docker-oracle-xe-11g/

Fork Juno branch from https://github.com/stackforge/nova-docker.git

  Recently Filip Krikava made a fork on github and created a Juno branch using
the latest commit + Fix the problem when an image is not located in the local docker image registry

 Master https://github.com/stackforge/nova-docker.git  is targeting latest Nova ( Kilo release ), forked branch is supposed to work for Juno , reasonably including commits after "Merge oslo.i18n". Posting bellow is supposed to test Juno Branch https://github.com/fikovnik/nova-docker.git

Quote ([2]) :-

The Docker driver is a hypervisor driver for Openstack Nova Compute. It was introduced with the Havana release, but lives out-of-tree for Icehouse and Juno. Being out-of-tree has allowed the driver to reach maturity and feature-parity faster than would be possible should it have remained in-tree. It is expected the driver will return to mainline Nova in the Kilo release.
 

Install required packages to install nova-dockker driver per https://wiki.openstack.org/wiki/Docker

Running Nova-Docker on OpenStack RDO Juno (CentOS 7)

  Recently Filip Krikava made a fork on github and created a Juno branch using
the latest commit +  Fix the problem when an image is not located in the local docker image registry

 Master https://github.com/stackforge/nova-docker.git is targeting latest Nova ( Kilo release ), forked branch is supposed to work for Juno , reasonably including commits after "Merge oslo.i18n". Posting bellow is supposed to test Juno Branch https://github.com/fikovnik/nova-docker.git
 

Quote ([2]) :-

The Docker driver is a hypervisor driver for Openstack Nova Compute. It was introduced with the Havana release, but lives out-of-tree for Icehouse and Juno. Being out-of-tree has allowed the driver to reach maturity and feature-parity faster than would be possible should it have remained in-tree. It is expected the driver will return to mainline Nova in the Kilo release.
 


Install required packages to install nova-docker driver per https://wiki.openstack.org/wiki/Docker
